The advent of the automatic laser pipe cutting machine has improved the cutting quality and efficiency of all kinds of stainless steel pipes and plates. From the emergence of any new technology to its popularization, the technology is constantly innovating. At the same time, traditional technology and The equipment will also be gradually replaced, just like the automatic laser cutting machine has gradually replaced the mechanical knife cutting method of the traditional cutting machine. Whether it is cutting square tubes, round tubes, special-shaped tubes or various stainless steel plates and other materials with flat and curved surfaces, the laser tube cutting machine has great advantages in terms of cutting quality and efficiency.
What are the methods of laser cutting? Laser cutting is the use of high-power focus, irradiated on the surface of the component, and chemical reaction to melt the material to achieve the purpose of cutting. The cutting methods include vaporization, melting, oxidation, etc. The specific cutting method is selected according to the characteristics of the material. The effect will be better.
This cutting method uses high-energy and high-density laser beams to heat the workpiece, and the material temperature rises to a certain level in a short period of time to vaporize to achieve the purpose of cutting. Generally, the heat of vaporization of materials is very large, and cutting machines for materials with different thicknesses need to be equipped with lasers of different powers. For example, precision laser cutting machines mainly cut some thin-walled or thin-plate metal materials. Therefore, the fully automatic precision laser cutting machine is mainly used in precision material industries such as electronic 3c, precision medical treatment, semiconductor integrated circuits, and auto parts.
During laser melting cutting, the material is heated to a certain temperature to melt, and a non-oxidizing gas is ejected through a nozzle coaxial with the beam, and the gas pressure is used to discharge the liquid metal to form a cutting edge. Laser melting cutting generally requires about 1/10 of the energy required for vaporization cutting. Generally, materials suitable for laser melting and cutting include alloys or active metals that are not easily oxidized, such as stainless steel, titanium, and aluminum.
Laser oxidation cutting uses laser as a preheating heat source, uses active gas such as oxygen as cutting auxiliary gas, and oxidizes the metal after the gas is ejected, releasing a large amount of oxidation heat, and at the same time melts the molten oxide and melt from the reaction zone Blow out to form the cut. Generally, the materials suitable for metal oxidation cutting include carbon steel, titanium steel and heat-treated steel and other easily oxidized metal materials.
There is also a laser scribing cutting method, which uses a high-energy-density laser beam to scan the surface of the material to cut a small groove on the outside of the material, and the laser continues to cut along this small groove, and finally achieves cutting. Effect, this cutting method is generally suitable for brittle materials, such as ceramics, sapphire, etc.
From the above introduction, we can see that each cutting method has its advantages, and different cutting methods are suitable for cutting different materials. According to the different processing materials, choose a fully automatic laser cutting machine that suits you, in order to achieve the highest work efficiency and work results. The types of cutting machines in our company include precision laser tube cutting machines and precision laser plate cutting machines, which can meet the processing needs of various materials, and can also conduct proofing experiments to ensure the cutting effect.
